hi,

"...thus they can be released at any time when reset input is low."

"I'm not with you there - PSEN needs to be held low during the falling edge of reset. So, it has to be released when reset is low."

Indeed, but read once again what they write: "...at any time..."
Of course my English is not good but for me the phrase "any time" does not mean "inside 24 clocks", does it for you?

Regards,
Oleg
